Phosphine-xA0-is a non-combustible-xA0-gas but burns in air at 150C producing P2O5-Impure phosphine-xA0-containing P2H4- catches fire when comes in contact with air-

Pure phosphine is not combustible while impure phosphine is combustible. This combustibility is due to the presence of :
$P_{2} H_{4}$
$N_{2}$
$P H_{5}$
$P_{2} O_{5}$

Phosphine is a non-combustible gas but burns in air at 150C producing $P_{2} O_{5}$ .

Impure phosphine (containing $P_{2} H_{4}$ ) catches fire when comes in contact with air.

Pure phosphine is not combustible while impure phosphine is combustible. This combustibility is due to the presence of :P2H4N2PH5P2O5
